Problem

On the island of Anarchygolfania they still use coins for all transactions. Each shop only keeps certain denominations of coins. When someone buys something, they always try to give the change back using the smallest number of coins possible. There is no centralized government to dictate what coins are legal tender so each shop uses a coins with different denominations.

The input will consist of one line per transaction. The first number gives the amount of change that must be paid back to the customer. The remaining numbers give the denominations of the coins that the store keeps.

The result should be a single line listing the required coins in increasing order of size. You can use more than one coin of each denomination.

If it is impossible to create the exact amount using only the given coins, return a line containing the hyphen symbol.

As an example, if the allowed coins have values 1, 7 and 12 and you must make the value 14, you should output "7 7". The solution "1 1 12" is not correct because it requires one more coin.
